Singlespeed & Fixed Gear - Original Plan for my Drivetrain....worth it?

So i had been planning to purchase an EAI superstar cog, Specialties TA chainring, and a supertoughness chain for my new build....this comes out to roughly $175

but after doing some reading about 1/8 vs 3/32 and kind of weighing my options i was thinking i can just do

sugino 130j chainring, EAI cog, KMC chainring for about $60.

Is there going to be a noticeable difference in performance between these two drivetrain options? should i just opt for the cheaper, or should it NOT cheap out on my build at the last minute?

whadda you guys think?

No need for an EAI Superstar if you're not racing on the drome. EAI's regular cogs are super nice as it is. Also, no real need for that spendy chain when KMC Kool chains run great with a little lube added. As far as the chainring, nicer chainrings are usually more round/true than lower quality ones, and this does make a difference in performance (not that noticeable assuming chainline is straight and everything else is in order but it's there) and safety (more leeway in chain looseness before you'll throw it).

Main things that matter on the street are that your drivetrain allows you to run a perfect or near perfect chainline, and that you maintain your chain through cleaning/lubing to ensure longevity in the drivetrain and also gain performance efficiency.

If you really want a higher-zoot cog for street riding, I recommend a Phil Wood instead of the EAI Superstar. You really don't need the latter unless you're doing some elite-level racing at the 'drome. On the other hand, the Phil wood is beautifully machined and finished, and mine has performed beautifully in ****ty conditions for over a year now with almost no discernible signs of wear.

yeah, any "good" cog (EAI/DuraAce/Phil) will last a loooong time, no need to go crazy.

I did a search on the forums and just found a lot of stuff that is confusing me in terms of the chainline....what am i looking for? How can i tell if my chainline is perfect or not? Is there a way to measure this?

Sheldon Brown's site has a good article on it.

you don't even need to have it exactly perfect. +/- 2mm is acceptable and will have negligible difference in performance.

but if you are in the process of getting new parts (as opposed to making some mish-mash of old parts work) its not tough to dial it in.

so you guys mentioned that i don't really need what i was originally planning to get unless i was planning on doing some crazy velo racing....but now i'm curious as to why it would be good for racing? Is it just minor improvements that wouldn't matter on a daily basis? Durability? or does it effect efficiency?

Think about it like this. A track bike is the most minimalistic bike you can ride, right? Well, when you're that stripped down to the essentials, everything is going to make a little difference that could buy you a little time in a race.

Also, actually racing your bike generally merits higher quality componentry anyway. The trick is figuring out which high quality components benefit someone who just appreciates quality vs. someone who is racing.

Superstar cogs and NJS chains are a waste of money, even for someone who is racing. The only speed you'll gain from these will be due to your lighter wallet.

thats why you don't pay what bens is asking for them. my njs chain costs as little as the non njs chains.

Most trackhubs place the cog in a plane located parallel to the centerline of the bike, 42.5 millimeters away. there is some slight variation - Sheldon Brown (http://www.sheldonbrown.com/chainline.html#hubs) has a database of measurements. Add the center-to-shoulder measurement of the hub in question to the chainline-from-shoulder measurement of the cog in question. Or, you can take the reasonable shorthand of assuming it's 42.5mm.

You want your chainring to also be 42.5mm away from the centerline of the bike. That will mean your chain runs straight.

So, use a ruler to measure how far your chainring is from the center of your seattube. See? it's easy. If it's more than a few millimeters off, you might want to look into corrective measures - getting a bb with a longer or shorter spindle.

To deal with this chainline issue, track cranksets have a "matching bb" that place them at the right spot for a good chainline.

Just eyeball it. Don't obsess over a "perfect" chain-line, you'll go nuts.

Whether or not higher-end track racing chains are worth the money to you is a matter of personal preference, but they are better made and will perform accordingly.

I get KMC 510HX chains for $11..thats KMCs most durable 1/8" chain. Show me an NJS chain that will get me more miles per dollar than that.

You might be right (although my experience with NJS chains tells me otherwise), but the performance improvement (if any) is not proportional to cost. NJS parts are expensive because Keirin is a gambling sport and everyone involved wants a piece of the pie. Anyone buying NJS parts should realize that while the parts are good quality, there are equally good and even better non-NJS parts available for a fraction of the cost.

Yes, to some extent you're paying for quality. And brand name. The OP needs to really decided what his needs are. For me, on my fixed Cross-Check, I'd rather buy $6 Z-Chains, run them for a 750-1000 miles and then toss them.

On the GTB, maybe I pay a little more, but since I only put maybe a 1000 miles a year on it, it doesn't merit a $50 chain. The Fixed 1x1 and SingleSpeed get the Cross-Check castoffs.

It just comes down to whether the increased quality is worth the increased price to the individual. To me it is, to OP it may or may not be.

i've not been happy with the lower-end kmc chains like the 410 and 510. the izumi eco is much quieter and less sloppy. if you're running a smallish chainring, or a higher ratio, dura-ace cogs are fine. they're only available up to 16t, which is why so many people use eai or otherwise. most track cranks come with a 48 or 49 ring, and you need a 16 to 18 cog to make that a streetable ratio for most people.

lol

this thread needs dutret

the real question is whether being the kind of person who runs pro stuff on the street is worth the money to you

try inflating your tires if you want increased efficiency

Just eyeball it. Don't obsess over a "perfect" chain-line, you'll go nuts.

well, if you're buying brand new parts for a ground-up build, you should be able to get a perfect chainline without going nuts. provided you get the right components for a 42 and tighten everything well it should, theoretically, just pop in.

as an aside, i have a pair of digital calilpers that are the ideal tool for measuring chainline. if you plan on doing a lot of builds or (especially) conversions, this is a good thing to have in your tool bucket.

NJS parts are expensive because Keirin is a gambling sport and everyone involved wants a piece of the pie.

That's totally wrong.
Theyre expensive in the USA because of the huge markup by the retailers in the states. In Japan, If you want good parts, buying NJS parts is about the cheapest way you can go in building your bike. I built my bike out of almost all NJS parts because it would save me money. Of course, i liked and trusted the parts too.

also, the dollar is weak.

That a new thing. The dollar wasnt weak a few years ago against the ¥ and they still marked the parts up drastically.
This just means that new NJS parts will just get more expensive as the US government continues to destroy our country.

-1000

this kind of attitude at an LBS leads to newbies dropping chains while bombing hills. bad times.

get calipers and do it right.

Agreed. It's not that hard to get a good chainline, and worth a little time to get it right.

it's a worthwhile $50. look here (http://oemproamtools.com/measuring/digital_cal.htm)

if you can work a straightedge, you can get acceptable results with that method, also.

true. i don't know about the markup. but i do know that prices have been "rising" in the past year, and i'm willing to guess that the weak dollar plays a part in that.

ooh! i too hate the US government! but last night's State of the Union was made much more bearable when we put a fake moustache on the TV screen, and drank every time it lined up with somebody's face. it was damn hilarious.

I had a Specialties TA chainring that was not round, creating a tight spot in the chain during crank rotation.
I tried adjusting but there was always a tight spot.
Switched a DA chainring and the problem was solved. The DA ring is smooth and quiet.
I've never had a problem with Sugino 75 chainrings either...
Just stay away from the Specialties TA.

yeah, i'd say that a good chainring is the best place to spend drivetrain money.

i have a TA Piste chainring that is very round. 130bcd for my stronglight cranks.

speaking of chainrings, does anyone have any experience with these?

No, but I can't say enough good things about FSA chainrings.

That's an AMAZING idea.

No, but I can't say enough good things about FSA chainrings.
Agreed, I had a 42t 110bcd one that I ran for quite awhile and it was awesome, but now I have 130bcd cranks and am looking to go back to FSA, I have a Sugino chainring now but it is wearing down pretty bad

the only gripe i have with my fsa products (carbon pro cranks, pro track 49t) is their branding is horrendous and everywhere. otherwise they're great.

I have those rings on my road bike. I chewed through the stock rings pretty quickly, but these have been holding up pretty well, even in the slop.

Salsa's single-speed rings are also made from 7075/T6, so you'd get pretty good wear from those as well.

hm, that's interesting
i had no idea.
what are some examples of expensive or over-hyped parts that aren't njs over there?

A Starrette ruler is all you need to hit +/- 1mm.

Just go to your LBS and ask to use their calipers. Anyone worth their **** should have a pair.

thanks for the help everyone!

I wish I had read this before I dropped $200 at the shop. My new drivetrain is the same as the OP's, with the exception of a Miche chain.

http://www.takizawa-web.com/shop-track06/track1-top.html

Hahaha, some local shop wants $340 for Sugino 75s. According to that site, they ought to cost $147.
